Coaches pick Viks 2nd in Big Sky — Portland State, coming off its first trip to the national playoffs in 15 years, was picked to finish second in the Big Sky by the league’s coaches, in a poll released Tuesday. Media members picked the Vikings, who finished second in the Big Sky last season, to finish fifth in the 13-team conference. Northern Arizona was the coaches’ and media’s pick to win the league. The Vikings, who were 9-3 overall and 6-2 in the Big Sky in 2015, will look to last year’s conference newcomer of the year, quarterback Alex Kuresa, to help them to their first back-to-back winning seasons since 2005-06.

Lesnar failed 2nd drug test — Brock Lesnar was informed his UFC 200 fight-night sample has the same banned performance-enhancing substance that he tested positive for on June 28, UFC announced Tuesday. An official with knowledge of Lesnar’s samples identified the banned substance as the fertility drug clomiphene, one of the two banned substances found in a June sample taken from former UFC light-heavyweight champion Jon Jones. Lesnar, 39, defeated No. 8-ranked heavyweight Mark Hunt by unanimous decision in the co-main event of UFC 200 on July 9. Last week, it was announced that the U.S. Anti-Doping Agency found Lesnar’s June 28 sample positive for a banned substance that has yet to be officially revealed by the Nevada State Athletic Commission. Lesnar remains under contract with WWE and is scheduled to participate in SummerSlam next month.
